Documentation suggests I should be able to get 1 Gbps speeds on a P2S connection, but I'm not. My test setup is as follows (also see diagram):
A speed test server in a VNET in US East
A VPN Gateway on the same VNET
A Windows 10 client in a different VNET in the same region
Without going through the VPN Gateway, the Windows 10 client sees speeds of 1.8 Gbps down and 1.6 Gbps up. However, going through the gateway, it gets about 150 Mbps down and 450 Mbps up. I don't seem to have many options at my disposal for configuring a P2S gateway, so I fear that I am out of luck. I have tried both OpenVPN and IKEv2 tunnel types.
My question: Is there a way to achieve Gigabit speeds through a VPN Gateway with a P2S connection?
My SKUs:
VPN Gateway: VpnGw2
VM SKUs: Standard D4s v3
